“It is important to note that with the media's help, with News4's help, that we were able to get onto this particular case," State’s Attorney spokesman Ramon Korionoff said.

Keller had tried to sell multiple cars to News4 employees who went undercover at a parking lot near Colesville Road and University Boulevard in Silver Spring, Md. However, Keller did not have a dealer’s license to sell cars in Maryland, leaving questions about whether any of the vehicles were inspected or safe to drive.

What to Know Before Buying a Used Car

Expert says as many as 80 percent of used cars sold through online classified ads are coming from illegal car dealers called "curbstoners." Three longtime car experts -- Eric Friedman, Director of Montgomery County s Office of Consumer Protection; John Creel, retired automotive crimes investigator; and Jack Fitzgerald, Chairman of Fitzgerald Automalls provide tips on what to know before buying a used car.

When asked if the cars were safe to drive, he said they were because, “I’ve driven them.”

When asked if they were inspected and would meet Maryland inspection, he answered, “They probably will. A lot of them have been inspected. They’re safe cars.”

At the time, Keller promised to show News4's undercover buyers his license, but never produced it.
“What I’m doing is not illegal,” he said.

Maryland’s Motor Vehicle Administration disagreed. After the I-Team's story aired, the state charged him with multiple counts of "conducting business" and "acting as a vehicle salesman" without a license.

“This particular individual was selling cars without a license and those cars were breaking down, they did not have warranties, they did not have the kinds of safety mechanisms and measures that should be required for automobiles sales," Korionoff explained.

Keller showed up to Montgomery County District Court Friday on crutches due to a foot injury to face the charges, and pleaded guilty to one charge. After the trial, I-Team asked him for comment and he responded, “Get out of my face.”

The judge gave Keller 12 months of supervised probation, a $500 fine and a warning -- if Keller is found selling cars again in Maryland, he could end up behind bars.

“We want to hold this defendant accountable and also send a message that is you should offend again, we can actually seek more time and a larger fine," Korionoff said.

Before he walked away from I-Team cameras, Keller had one last message, “Plenty worse things somebody could be out here doing, man. Y’all better take heed."
